By "parameters you optimize in the nls() call" I mean `a`. `a` does
not seem to be used in the calculation of `fx`. If it were, it would
have to look like:
fx <- function(x1, x2, a) { ... }
nls(y ~ a*(sin(x2) + fx(x1, x2, a)), start = list(a = ...))
so that nls() would be able to check different values of `a`.
